• A new statue of former US President Ronald Reagan was unveiled in Grosvenor Square near the US embassy on Monday, 4th July. The 10 foot tall bronze statue of the president, who died in 2004, was unveiled at a private ceremony by the Foreign Secretary William Hague – former US Secretary of State Condoleezza Rice were also among the more than 2,000 people who attended along with current US ambassador Louis Susman (a frail Margaret Thatcher was reportedly too frail to attend). Commissioned by the Ronald Reagan Presidential Foundation, the statue is the work of sculptor Chas Fagan. Its unveiling is one of a series of events marking the centenary of the birth of the former actor turned politician.

• Pall Mall and St James Street in the West End were opened to two-way traffic this week for the first time in 50 years. The changeover came into effect last Sunday morning. The roads were made one-way in 1963 under a scheme to deal with increasing traffic in the area. But it has been reopened in the first stage of a £14 million overhaul of traffic around Piccadilly Circus – home to world-famous neon billboards and the Eros Statue. The area is visited by 200,000 every day.
